Complex Ta-Nb-Ti-Sn minerals associated with late pegmatites, Parguaza Bartholith, Bolivar State, Venezuela

摘要

Complex Ta-Nb-Ti-Sn minerals have been studied in association with late pegmatites affecting the Parguaza Batholith in the zone of Boquerones-Horeda, Bolivar State, Venezuela. The quartz pegmatite constitutes of extensive, highly weathered bodies of simple milky quartz enriched Tantalites-Columbite, Cassiterite, Strueverite and Ixiolite. These minerals are associated with typical late metallisation process affecting the Parguaza Batholith.
